The main purpose of this research is exploring the tipping points for a radical shift in supplier (dis)satisfaction. This study identifies triggers and links them to consequences for the buyer–supplier relationship.

The Critical Incident Technique (CIT) was used to interview Dutch supplier representatives in the infrastructure sector, resulting in rich descriptions of 29 critical incidents, extracting first-hand information.

Safety issues, technical disputes and recruitment of supplier’s technical staff have been identified as tipping points for suppliers to become dissatisfied. Implementing performance-based contracting is another critical incident that caused irritation and disappointment. On a more operational level, dissatisfaction was provoked by tender errors and price discussions with the buyer. This study also identified tipping points by which dissatisfied suppliers abruptly turned into satisfied suppliers. The effect of a solution-oriented buyer intervention appears to be most powerful if this behaviour transcends prior expectations.

Consequences of misunderstandings and discussion between supplier and buyer may be manageable or repairable, depending on the causes and triggers that influenced a supplier’s dissatisfaction. An early warning system could prove its worth, so that buyers are not faced with unpleasant surprises.

Despite the growing number of studies, processes of how antecedents lead to supplier (dis)satisfaction are not well understood. Antecedents are predominantly investigated by cross-sectional survey data, giving little insights into micro-processes and actual interaction between buyers and suppliers. Although CIT has been applied in many disciplines, the technique is hardly used within the context of purchasing and supply management research.

This paper aims to introduce a systematic computing and analytical procedure that is applied to the co-author network to identify the temporal evolution and growth of research collaborations in the area of e-governance. The empirical analysis of the temporal co-author network can trace the emerging authors and knowledge bursts over time.

The study applied social network theory to trace the author collaboration patterns in the domain of e-governance. Analysis of the co-author network using micro and macro parameters was done to trace the temporal evolution of the author collaborations.

E-governance is a multi-disciplinary research domain split over streams of management, politics, information technology and electronics. Hence, research collaborations play a significant role in its advancement. The knowledge sharing between individual authors, institutions and groups through research collaborations, resulting in extensive sharing of data, equipment and research methods, has boosted research activities and development in e-governance. In this paper, the authors systematically analyse the current scenario of research collaborations in the area of e-governance using co-author network to estimate its impact on the advancement of the field. The authors also analysed the temporal evolution of the co-author networks, which show remarkable growth of research collaborations in the domain of e-governance from the year 2000.

The co-author network analysis is only a proxy measure for the analysis of research collaborations. The names of the authors and the university affiliations used in the article are as retrieved from the research repository of Scopus. The degree, citations and other parameters related with authors have scope only within the environment of the co-author network used in the analysis. The criteria used in the study is limited to the degree of research collaborations and the number of co-authored publications in the giant component of the co-author network.

Institutions, authors and governments can trace and select suitable topics and choose research groups of co-authors over the world for future research collaborations in e-governance. The knowledge about the emerging and most discussed topics gives an overview of the global research trends of e-governance.

The study identified the evolution of creative collaborations in e-governance in the global perspective. The methodology introduced here is helpful to detect the proficient and productive author collaborations and the spectrum of related e-governance research topics associated with them. As the author collaborations can be mapped to the institutional and country-level collaborations, the information is helpful for researchers, institutions and governments to establish the best collaborations in e-governance research based on the author proficiency, collaboration patterns and research topics as per the requirements.

The paper introduces a novel research methodology using temporal analysis of co-author network to identify the evolution of research patterns and the associated research topics.

Rising public scrutiny has? brought new demands for science communication. Especially, incidents of falsification, fabrication, and plagiarism have recently come to question academic integrity and legitimacy in Germany. Focussing on a prominent plagiarism case that revolved around the former Minister of Science and Education’s dissertation, the purpose of this paper is to investigate the communication strategies of the Düsseldorf University as it navigated the complex challenges of the crisis situation.

The analysis is based on a rhetorical analysis of the public discourse of the University Düsseldorf in the context of the plagiarism crisis.

The study finds that the university responded to the crisis by focussing on legitimating the legal and administrative process by which it evaluated Schavan’s dissertation and revoked the degree. In turn, this focus neglected restoring the threatened reputation of graduate education and of scholarship itself. Ultimately, the crisis communication of the university worked to undermine the premises and goals of science communication.

Future research should focus on case studies of crisis communication by academic and research organizations as well as on investigating the effects of crisis rhetoric on public trust in and on understanding of academic research. The study suggests that it is worthwhile for crisis and science communication scholars to work to develop distinct frameworks for science communication in crisis and crisis communication in science that account for the unique tensions and duality of needs in this arena.

The study contributes to the understanding of the intersections between crisis communication and science communication. Especially, it underlines the importance of developing distinct frameworks for science communication in crisis and crisis communication in science that account for the unique tensions and duality of needs in this arena.

Globalization requires business leaders who can manage effectively in multicultural environments. Although many organizations assume leaders will enhance their multicultural skills through international assignments, it is unclear how leaders translate these international experiences into knowledge and skills that enhance their effectiveness. Based on experiential learning theory (ELT), we propose that cultural intelligence (CQ) is an essential learning capability that leaders can use to translate their international experiences into effective experiential learning in culturally diverse contexts.

Since the mid-2000s, there has been a marked resurgence in Hollywood action films featuring older male heroes, predominantly showcasing stars ranging from their mid-fifties into their seventies. This ‘geri-action’ cycle – a less-than-kind label that combines geriatric and action – has revitalised the careers of aged action stars such as Sylvester Stallone and Arnold Schwarzenegger. A core element of the cycle, beyond action franchise revivals and all-star ensembles featuring stars from the 1980s and 1990s, has been the emergence of late-career action turns by ageing Hollywood actors in globally successful French-produced, Hollywood-style action films. Part of a larger trend in French cinema towards the production of films in a distinctly commercial register, the ‘globalised’ aesthetic of French action film cannily mimics Hollywood action film style and aesthetics. These French-produced geri-action films are the roots of the cycle, represent some of its biggest box office successes and have transformed the career of several acclaimed recent-to-action Hollywood stars, exemplified by the prolific late action career of Oscar-nominated actor, Liam Neeson, most notably across three Taken films (2008–2014, EuropaCorp). Despite this, these French-produced geri-action films have predominantly been examined as a Hollywood and American phenomenon.

Geri-action quickly became synonymous with 1980s Hollywood action cinema's white male ‘hard bodies’, who are still widely understood to diagnose national anxieties and social ills – and violently embody their so-called “cures”. These French geri-action films similarly feature protagonists who forcefully struggle against perceived threats to the cultural position of traditional (white) masculinities and professional and paternal redundancy. Yet they also showcase deep-seated European anxieties about the threat of porous borders, immigration and social change, presaging a later shift in the cycle in Hollywood. Focusing on films that have received comparatively less scholarly attention, Taken 2 (2012), 3 Days to Kill (2014) and The Commuter (2018), this chapter examines the productive confluence of lower budget French-produced geri-action films and their ageing recent-to-action stars. These films depend on their stars to fortify their globalised Hollywood aesthetic and the stars' personae permit efficiencies such as clipped pacing. At the same time, budget constraints enhance the action performance of recent-to-action stars as unadorned, visceral and authentic-feeling. The films often stage fight sequences in confined, everyday spaces of work and tourism with ageing heroes who must creatively ‘make do’ with objects available to them. Equally, stunt coordination and choreography, editing and sound design make ageing and less experienced action performers appear to move faster and hit harder. Taken together, French-produced geri-action and its recent-to-action stars have transformed not only who stars in ‘Hollywood’ action cinema but who produces it.

The purpose of this study is to analyze the intelligent fault diagnosis method of rolling bearing.

The vibration signal data of rolling bearing has long time series and strong noise interference, which brings great difficulties for the accurate diagnosis of bearing faults. To solve those problems, an intelligent fault diagnosis model based on stacked denoising autoencoder (SDAE) and convolutional neural network (CNN) is proposed in this paper. The SDAE is used to process the time series data with multiple dimensions and noise interference. Then the dimension-reduced samples can be put into CNN model, and the fault classification results can be obtained by convolution and pooling operations of hidden layers in CNN.

The effectiveness of the proposed method is validated through experimental verification and comparative experimental analysis. The results demonstrate that the proposed model can achieve an average classification accuracy of 96.5% under three noise levels, which is 3-13% higher than the traditional models and single deep-learning models.

The combined SDAE–CNN model proposed in this paper can denoise and reduce dimensions of raw vibration signal data, and extract the in-depth features in image samples of rolling bearing. Consequently, the proposed model has more accurate fault diagnosis results for the rolling bearing vibration signal data with long time series and noise interference.
